DNS Monitoring for SOC 2 Compliance

What SOC 2 Requires

SOC 2 is built around five Trust Services Criteria: Security, Availability, Processing Integrity, Confidentiality, and Privacy. During a Type II examination, auditors review your controls over a period of time, typically 6 to 12 months, looking for evidence that your monitoring and change management processes actually work.

DNS changes directly affect two of these criteria. A hijacked DNS record is a security incident. A misconfigured record can take down your service. Auditors want to see that you're detecting these issues, not discovering them after a customer complaint.

How ZoneWatcher Supports Your SOC 2 Controls

Security (CC6.1, CC7.1, CC7.2)

ZoneWatcher continuously monitors your DNS records and alerts your team immediately when any change is detected. This covers the common criteria around logical access controls and system monitoring. Every change is logged with timestamps, previous values, and new values, giving your auditor a complete picture of what changed and when.

Availability (A1.1, A1.2)

ZoneWatcher maintains full backups of your DNS records that can be exported as Bind Zone files or CSV. If a critical record is deleted or modified incorrectly, you have the data to restore it. This demonstrates your capacity to recover from DNS-related incidents that could affect service availability.

Confidentiality (C1.1)

TLS/SSL certificate monitoring through Certificate Transparency logs detects unauthorized certificate issuances for your domains. If someone obtains a certificate for your domain without authorization, ZoneWatcher alerts you, helping protect the confidentiality of data in transit.

What Your Auditor Sees

When your SOC 2 auditor asks for evidence of your monitoring controls, you can point to ZoneWatcher's change history. Every DNS modification across your domains is recorded with:

• The exact record that changed (type, name, value)
• The previous and new values
• When the change was detected
• The notification that was sent to your team

This is continuous, automated evidence collection. No spreadsheets to maintain, no manual log reviews to schedule. The monitoring runs around the clock, and the history is always available for the examination period.

Beyond the Audit

SOC 2 compliance isn't just about passing an examination. The controls you implement should genuinely protect your organization. DNS hijacking, cache poisoning, and accidental misconfigurations are real threats. ZoneWatcher detects these issues in real time, so your team can respond before they become incidents on your SOC 2 report.
